Deconz - all devices being switched on together

Tags: #<Tag:0x00007f32731dcd18> #<Tag:0x00007f32731dcb10> #<Tag:0x00007f32731dc8b8>

Apologies in advance as I am not sure what information might be useful to include, however I have recently started to experience an odd issue whereby all devices linked to Deconz suddenly collectively turn on. On one occasion all the associated colour change light bulbs also switched red. I am unsure as to whether this is an error or something more concerning from a security perspective.

When I look at a device in HA it will report that the device was ‘turned on’ but give no further details, unlike if a user (or automation) interacted with it - eg “Steve”.

My HA is available for remote access via DuckDNS / NGINX. Zigbee devices are connected via a Conbee II stick and Deconz running firmware 26580700.

At that time there was no intervention by anyone who should have access and no automatons I am aware of should be running which do this. Home-assistant.log contains no info on the event. The Deconz log at that particular moment reports:
